Abstract. Restoration of the ensemble of parks, palaces and fountains of Peterhof (Petrodvorets) near St. Petersburg (Leningrad), Russia, is one of world-renowned restoration projects of the post - World War II period. However, little has been analysed of this unique restoration experience. This paper presents a specific episode in the history of this restoration project.

The Peterhof ensemble is a complex historic site which includes many palaces, structures and fountains covering 18 square km of parks and gardens. The Grand Palace, - the central and the largest building of this ensemble, was built at the edge of a natural terrace, with a view to the sea (the Gulf of Finland) and the Lower Park at the foot of the terrace. This dominant spatial-architectural role of the Grand Palace was emphasized by its highest elements – two cupolas of its eastern and western parts. The cupolas were heavily damaged during World War II and shape reconstruction had to be undertaken for their restoration. The restoration of cupolas was one of the first and important steps in the restoration of the Peterhof ensemble.

This paper focuses on the approach, methodology and the selected technological aspects of the restoration of cupolas of the Grand Palace, with a view to their interpretation at the time of restoration of cupolas (1950-s) as well as to modern restoration principles. It shows the process and methods of non-digital reconstruction of the shape of 3D object aided by non-digital models, unique decisions and techniques.
